FAQ

Is this calculator free?

Yes, completely free. Keine Registrierung, keine Werbung, no limits.

Was is the difference between population and sample standard deviation?

Population std dev uses N (all data), while sample std dev uses N-1 (subset estimate). Use population when you have all data, sample when working with a subset.

Wie does outlier detection work?

We use the 1.5 × IQR rule: any value below Q1 - 1.5×IQR or above Q3 + 1.5×IQR is flagged as an outlier.

Can I paste data from Excel or a spreadsheet?

Yes! Einfügen directly — commas, spaces, tabs, and new lines are all auto-detected.

Is my data private?

Absolut. Alle Berechnungen happen innerhalb Ihres Durchsuchenrs. Nichts wird gesendet to any server.
